One for the Darwin gurus.
I seem to have wrecked my login setup by monkeying around with the /etc/ttys file. No, I didn't back it up. Yes, I am an idiot.
I was commenting in and out the two console lines (line 8 and 9 or thereabouts) to boot into command line mode. That worked fine.
Now when I tried to restore those two lines to their original configuration and reboot, I got the grey apple, the blue screen, the Welcome/progress bar, then a couple of rows of white text on a black background appear over the blue screen, saying "Darwin/BSD (My-Computer.local.) (console) a couple more lines and then it hangs.
I don't have a backup of the original /etc/ttys file. Am I stuffed or what?
